HERNIAL TRUSS.

SPECIFICATION forming part of Letters Patent No. 296,300, dated April 1, 1884.

Application filed October 29, 1883. (ModeL) To aZZ whom, it may concern.-

Be it knownthat I, WVILLIAM L. TUCKER, of Syracuse, in the county of Onondaga and State of New Yorlghave invented certain new and useful Improvements in Hernial Trusses, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure 1 is a perspective of the truss from the rear; Fig. 2, a longitudinal section of the pad; Fig. 3, a cross-section of the slotted faceplate; Fig. 4, a perspective of the swiveled hook; Fig. 5, a section of the hinge created by the slotted face-plate and the hook.

My invention relates to that class of trusses in which a base-plate is hinged to the pad and a continuous pressure is exerted upon the pad in use by the compression of a springbetween the base-plate and the pad.

It consists of the various elements and combinations of devices hereinafter specifically set forth in the claims.

A represents the pad.

13 is the base-plate, hinged to the back of the pad, and having a spring, "a, between it and the back of the pad, the spring lying partly in a recessin the pad.

0 is the slotted face-plate, secured to the base-plate by the set-screw b, by which it can be set to any point of the arc of the bottom of the base-plate for adjustment of the truss. This face-plate consists of a base, a, diverging slots d, and side bars, 6. It is constructed of the tapering longitudinal outline, in order to give the greater length of slots, and so that the leverage action of the base-plate B upon the spring a will be increased, thereby holding the pad at both top and bottom securely in position, and obtaining the maximum pressure of the pad with the minimum strain upon the belt, and thus reducing the pressure of the belt upon the body of the wearer. The attainment of these results is aided by means of the hook D, swiveled or pivoted upon the belt-adjusting device E. This hook is constructed of about the shape shown in the drawings, with one arm mounted upon the pivot h. The other arm is made of sufficient depth that it will not easily unhook.

The adjusting device E consists of the ordinary lever biting or compressing device in common use upon suspender-buckles, by which the webbing is held by compression against a plain surface on the opposite side of the webbing to that upon which the pressure is applied. I commonly use teeth upon the pressure-bar, which bite into the webbing.

F is the belt, usually constructed of webbing.

The effect of the swiveled hook is to take up the motion of the movements of the body of the wearer, so that such movements will notdisturb the pad or cause it to slip, the whole combination of parts creating a device which is flexible and yielding to any movement of the person, thus avoiding any displacement of the pad.

The pad A is constructed with a flat back, and a face rounded outward from the back on the sides and head, about as shown in the drawings.

The base H of the pad is constructed with the face extending back beyond or overhang ing the adjacent portion of the back of the pad, and rounded outward from the outer edge of the overhang 1;, upward to. the face, as shown in Fig. 2. This beveled base and overhang is of especial benefit in the treatment of hernia adjacent to the pubicbone, for the reason that all pressure of the pad upon the pubic bone and compression of the spermatic cord and neighboring'veins between the pad and that bone is avoided, because the edge of the overhang t will lie behind or beneath the edge of that bone and the beveled surface adjacent to the edge of it, w representing the point of greatest pressure. The side bars, 6, of the face-plate G are elevated above the plane of the body of the plate in order thatthe slots may better receive the hook.v

A result approximating to that obtained by me by the use of the swiveled book can be obtained by the use of a rigid hook and a swivel upon the base-plate, with which the hook e11- gages in any ordinary manner.

Having thus described my device, what I claim as my invention, and desire to secure by Letters Patent, isy 1. In a hernial truss, a swiveled hook connecting the belt to the pad, constructed sub stantially as above described.
